Applicatiqhnsvgmberl19, [1935, 'sefisinatoicts Y Y Gianni- A (c1. 16s-29) V :This invention relates toa re extinguishing system, 'and has for. an object lto .provide a sys- .tem `or structure which may be applied'or asso-Y ci'atedwith a single room or with many rooms and :s caused to act automatically 'or by ahand control.

Another object of the invention is tojprovidea lre extinguishing system` adaptedv for a single room 'wherein the parts are mounted so as to dis-V tribute an extinguishing fluid which will produce lio a 'smothering gas when the device is functioning. An additional object, more specically, is to tprovide a container' at the 'top of 'the room with f electric control means forcausing the same to function.. la In the accompanying drawings: ,Y

Fig. 1 Vis a vertical sectional view through'a tank and associated parts forming the principal part of the invention, the same being shown applied to a ceiling of a room;

20 Fig. 2 is a bottom plan view of the structure shown in Fig. 1;

Fig.' 3 is a bottom plan View of the tank shown in Fig. 1; and Y Fig. 4 is a diagram showing the electrical con- 25 nections and certain associated devices.

Referring to the accompanying drawings by numerals, I indicates a spider which is provided with an outer ring structure 2, a central section 3, and a number of spokes 4. Suitable screws 5 30 secure the spider I permanently to the ceiling '6 and on this spider all of the other parts are mounted. In Fig. 1 it will be observed that the tank 'I is provided with a flange 8 through which the various machine screws 9 extend for clamp- 35 ing the container rigidly to the spider l. The container at the upper central part is provided with a chamber I in which the electric motor II is positioned, said motor having a flange I2 through which the screws I3 extend, said screws 40 being threaded into the spider I. The tank 'I is also provided with a central tube I4 through which the armatureshaft I5 extends whereby this shaft may be clamped by any suitable means, as for instance the set screw I6, to the hub I1 of a distributing member I8.

It will also be noted that the side wall of the container is provided with an annular groove I9 in which a rubber or other packing is fitted, whereby liquid can not pass upwardly Within the side wall 2l of member I8. The side wall 2l is provided with an annular iiange 22 overlapping the flange 23 of a ring bracket 2li, whereby the various anti-friction balls 25 may be po- 55 sitioned between the two flanges and thereby rotatablylsupport .member I8. Member I8 at the lower .part 'is provided'with a number of a ,pfer,` tures ,'28 Aand at the periphery witha numbero'f apertures 21,. .It will be noted that lthelower part or lbottom of .member "I8 'is spaced from 'the boti5:

accommodate the `sharp pointed ends 'or theY cut-y 15" ters 35V andlt which 'are clamped to -member VIt! by 'suitableboits 'or rivets 31 and 3'8.' l Q -`When the parts' are in 'the position shown in Fig. 1 and motor II begins to function it will rotate member I8 and the rst revolution will 20 result in the cutters or knives 35 and 36 cutting Y through the tracks 3`I and 32. This will allow the liquid to freely pass downwardly to chamber 29 and be sprayed or distributed as the distributing or spray member I8 continues to rotate. 25 The liquid 38 is intended to be some form of re extinguishing solution or liquid which will produce a smothering cloud adapted to deprive the i'lre of oxygen whereby it will be extinguished. As the device is carried by the ceiling of the room 30 the spraying of the liquid at that point will result in a desired conversion of the liquid into a smothering gas. As this gas is heavier than air it will gradually move downwardly and extinguish any fire that might be in the room. After the device has once functioned it will be necessary to remove member I8 and place a new tank in position with a new supply of liquid. After this has been done member I8 is replaced and the device is ready for a second use. 40

The device may be caused to function by various means, but preferably by one or more thermostatic switches and also by a manually actuated switch. As shown in Fig. 4 the motor II is connected by wires 39 and 40 with source of current 45 4I through either of the switches 42er 43. Also a sounding device, as for instance bell 44, is connected with source of current 4I and the circuit thereof is closed by either of the switches 42 or 43. It will be understood that either of the switches may be placed at any desired point in a room and, if desired, a number of the automatic heat control switches may be connected up to the same circuit so that if a re starts in any part of the room near a switch the response will be almost imspider adapted to be secured to the ceiling of a I I will begin to rotate and upon the rst rotation Y the tracks 3l and 32 will be cut so that the fluid will immediately begin to ilow into chamber 29. As member I8 continues to rotate the liquid will be sprayed so as to be evaporated or formed into a. cloud whereby the re is extinguished.

I claim:

1. A fire extinguishing system including a iixed liquid carrying tank, arotary` liquid distributing member forv distributing liquid from saidv tank, a cutter carried by said distributing member and positioned to cut an opening in said tank when the distributing member is rotated, an electric motor for rotating said distributing member, and a plurality of means for closing the circuit of said motor, one of the last mentioned means being a manually actuated switch andthe other a heat actuated switch. .7; Y

2. A lire extinguishing system including a liquid container, a rotating"distributingmember partly surrounding the container and'provided with distributing apertures, a cutting structure carried by said distributing -memberjand posi,- tioned to"'cut yan opening in said container when the distributing member is rotatedQandv an electric motor connected with the distributing member for rotating the same. Vj f 3. A fire extinguishing system `'including a room, a container adaptedto be permanently connected with said spider, an electric motor connected permanently'tojthecenter of said spider, said container being adapted to be provided with a re extinguishing liquid, said container also being provided witha passageway extending vcentrally therethrough, said motor having a shaft extending throughsaid passageway, said container having a pair of parallel tracks of comparatively thin material in the bottom, a pair of knives adapted to cut said tracks so that part of the bottom will move away from the remaining part for permitting said liquid to ow from the container, a distributing member having an annular side wall and a foraminous bottom, means for rigidly securing said bottom to said shaft so that the distributing member will rotate with said shaft, and means for clamping said knives to said distributing member. Y

V4. In a fire extinguishing system, a xed container, a rotating distributing member having an annular wall surrounding said container, means coacting with said wall for rotatably supporting the distributing member, said annular wall merging into a substantially fiat bottom having perforations, said Wall being also provided with perforations near said bottom, a cutting structure carried by said bottom adapted to cut part of the bottom of said container when the vVolistributin'g member is rotated, and means for rotating said distributing member. Y Y

5. A device for spraying fire extinguishing liquid from the ceiling of a room comprising a liquid container, means for cutting the bottom of the. container to allow the liquid to flow there-v from, a foraminous rotating member for Vdistributing the liquid from the container over a wide area, said cutting means being carried by said rotating member and positioned to cut part of said bottom when said foraminous rotating member is rotated, and means for rotating said rotating member. v
